Abstract
OBJECTIVES The aim of this study was to assess the mid-term outcomes of the use of drug-coated balloons (DCBs) to treat infrainguinal peripheral arterial disease (PAD) in patients with dyslipidemia. METHODS BIOLUX P-III is a prospective, international, multicenter, all-comers registry-based study that was conducted at 44 sites with follow-ups at 6, 12 and 24 months. The present study is a subgroup analysis comparing the outcomes associated with endovascular revascularization with those associated with Passeo-18 lux DCBs in patients with and without dyslipidemia. The proportions of patients free from major adverse events (defined as device- or procedure-related mortality within 30 days, clinically driven target lesion revascularization (CD-TLR) and major target limb amputation), target vessel revascularization, and patient-reported outcomes within 24 months postintervention were compared between the two groups. RESULTS A total of 876 patients with symptomatic PAD who underwent peripheral revascularization with DCBs and had information on their dyslipidemia status were included; 588 of those patients had dyslipidemia. There was no difference in the proportion of patients free from MAEs between the groups. The percentages of patients who were 6, 12 and 24 months free from CD-TLR were significantly lower in the dyslipidemia group than in the nondyslipidemia group (86.3% vs 91.9% at 2 years, p = .0183). Similarly, the percentage of patients free from target vessel revascularization was lower in the dyslipidemia group at all timepoints (83.3% vs 89.3% at 2 years, p = .0203). There was no difference in mortality or major or minor limb amputation rates. Other secondary outcomes were similar between the groups. CONCLUSIONS Compared to those without dyslipidemia, patients with symptomatic PAD and dyslipidemia who underwent revascularization with a Passeo-18 lux DCB had greater rates of CD-TLR and TVR. However, having dyslipidemia did not increase the risk of mortality or limb amputation. CLINICAL TRIAL REGISTRATION NCT02276313.

Network Meta-analysis of Randomised Controlled Trials Comparing the Outcomes of Different Endovascular Revascularisation Treatments for Infra-inguinal Peripheral Arterial Disease Causing Chronic Limb Threatening Ischaemia. Eur J Vasc Endovasc Surg 2024; 68:246-254. [PMID: 38754723 DOI: 10.1016/j.ejvs.2024.05.014] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/01/2023] [Revised: 04/19/2024] [Accepted: 05/09/2024] [Indexed: 05/18/2024]
Abstract
OBJECTIVE The aim of this study was to compare the efficacy of different endovascular revascularisation procedures for treating chronic limb threatening ischaemia (CLTI) using network meta-analysis (NMA). DATA SOURCES The databases PubMed and Cochrane Central Register for Controlled Trials were searched on 14 March 2023. REVIEW METHODS A NMA of randomised controlled trials (RCTs) reporting the efficacy of different endovascular revascularisation techniques for treating CLTI was performed according to PRISMA guidelines. The primary and secondary outcomes were major amputation and death, respectively. Random effects models were developed and the results were presented using surface under the cumulative ranking curve plots and forest plots. A p value of ≤ .050 was considered statistically significant. The Cochrane collaborative tool was used to assess risk of bias. RESULTS A total of 2 655 participants of whom 94.8% had CLTI were included. Eleven trials compared plain balloon angioplasty (PBA) vs. drug coated balloon (DCB) angioplasty (n = 1 771), five trials compared bare metal stent (BMS) vs. drug coated stent (DCS) (n = 466), three trials compared atherectomy vs. DCB (n = 194), two trials compared PBA vs. BMS (n = 70), one trial compared PBA vs. atherectomy (n = 50), and one trial compared BMS vs. DCB (n = 104). None of the revascularisation strategies significantly reduced the risk of major amputation or death compared with PBA. Using the network estimates, GRADE certainty of evidence for improvement in major amputation outcomes for DCB was moderate, for atherectomy and BMS was low, and for DCS was very low compared with PBA. Risk of bias was low in 16 trials, of some concerns in six trials, and high in one trial, respectively. CONCLUSION There is no current evidence from RCTs to reliably conclude that BMS, DCB, DCS, or atherectomy are superior to PBA in preventing major amputation and death in patients with CLTI. Larger comparative RCTs are needed to identify the best endovascular revascularisation strategy.

Ann Vasc Surg 2024; 109:35-46. [PMID: 39019254 DOI: 10.1016/j.avsg.2024.06.013] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/04/2024] [Revised: 05/10/2024] [Accepted: 06/05/2024] [Indexed: 07/19/2024]
Abstract
BACKGROUND The treatment of chronic limb-threatening ischemia (CLTI) involves a broad spectrum of therapies including many new and emerging techniques. To standardize the results of studies examining this pathology and to allow critical analysis and comparison between studies, the Society for Vascular Surgery (SVS) recommended reporting standard guidelines for the endovascular management of CLTI in 2016. Research studies that do not adhere to complete reporting standards are often more ambiguous in impact and external validity, leading to bias and misinformation that has potentially damaging effects on clinical decision-making. We thus sought to examine adherence to and factors associated with noncompliance with these recommended guidelines. METHODS A literature database search was conducted to include all clinical trials, randomized controlled trials, and retrospective comparative studies written in English examining the endovascular treatment of peripheral artery disease (PAD)/CLTI from January 2020 to August 2022. Systematic reviews, case reports, and meta-analysis were excluded. The manuscripts were reviewed for adherence with the SVS guidelines (overall and by guideline subcategories based on demographics, treatment methods, and outcomes), and factors associated with this adherence were determined. These data were used to calculate descriptive and comparative statistics. RESULTS Fifty-four manuscripts were identified from this time frame. On average, articles reviewed reported on 42.0% of the SVS reporting standards (range, 25.0-65.2%, Fig 1) with 74.1% of articles (n = 40) not adhering to at least 50.0% of the standards. Manuscripts most completely followed guidelines regarding "patient factors" and were least likely to demonstrate adherence to the description of CLTI and study complications. Within the guideline subcategories, complete adherence to guidelines was not demonstrated in any manuscript in stent trials, disease outcome measures, technical outcome measures, patient factors and critical limb ischemia description, and complete adherence rates within the other subcategories was low (range, 5.6-18.6%). Studies conducted within the United States and those with industry sponsorship were more likely to adhere to >50% of the reporting standards (P < 0.05). Journal impact factor, year of publication, and number of authors had no correlation to the percent adherence to guidelines in specific categories or adherence overall. CONCLUSIONS Adherence to reporting standard guidelines for endovascular treatment of lower extremity PAD specifically outlined by the SVS is suboptimal regardless of the quality of the journal the research is published in. Increasing adherence to reporting standards to provide a framework for comparison of studies across techniques used should be prioritized by authors, journal editors, and vascular societies.

Abstract
CLINICAL IMPACT This retrospective observational registry trial combines national registries for vascular surgical procedures and diabetes mellitus to clarify results of drug eluting technology in treating diabetic subjects with intermittent claudication or chronic limb threatening ischemia compared to treatment of non-diabetic subjects. As earlier proposed and showed in this trial, there may be an implication for a beneficial treatment efficacy with drug eluting therapy in the diabetic population with PAD compared to the non-diabetic population. A finding worth further exploration.

Abstract
Peripheral arterial disease (PAD) represents one of the most prevalent cardiovascular disease processes and carries a high burden of morbidity and mortality. Patients with chronic limb-threatening ischemia (CLTI), the most severe manifestation of PAD, have the highest rates of cardiovascular morbidity and mortality of the overall PAD population. Patients with below-the-knee (BTK) PAD have an increased propensity toward CLTI due to small-vessel caliber and the frequently comorbid conditions of end-stage renal disease and diabetes mellitus, which tend to affect small artery beds preferentially. For those with BTK PAD with CLTI, the standard of care is revascularization. Early revascularization was performed using surgical bypass. However, endovascular techniques, starting with percutaneous transluminal angioplasty and expanding to the modern armamentarium of adjunctive devices and therapies, have become standard of care for most patients with CLTI due to BTK PAD. In this review, we will discuss the modern surgical and endovascular approaches to revascularization, as well as devices that are currently in development or preapproval study for the treatment of BTK PAD.

Abstract
BACKGROUND The aim of this study was to evaluate the efficacy and safety of paclitaxel-coated balloons (AcoArt Orchid) in treating dysfunctional arteriovenous fistulae. METHODS The drug-eluting balloon for arteriovenous (AV) fistula in China trial was a prospective, multicenter, randomized controlled study. Patients who had ≥50% venous stenosis of the AV fistula and symptoms indicating significant hemodynamic changes were included. After successful predilation with a high-pressure balloon (residual stenosis ≤30%), patients were randomized 1:1 to either a paclitaxel-coated balloon or an uncoated control balloon. The primary efficacy outcome was assessed at 6 months, and safety assessment was conducted within 30 days of the procedure. The 12-month results were also analyzed. RESULTS The study included 244 patients, equally distributed between the two groups. The primary target lesion patency was 91% (106/116) for the drug-coated balloon (DCB) group and 67% (79/118) for the plain balloon catheter group, representing a difference of 24.63% (95% confidence interval, 14.68 to 34.58; P < 0.001). The secondary efficacy end point was primary target lesion patency at 12 months, which was 66% (74/112) for the DCB group and 46% (52/112) for the plain balloon catheter group (95% confidence interval, 6.57 to 32.08; P = 0.004). The mean number of reinterventions per patient to maintain target lesion patency during the 12 months after the index procedure was 0.39 (48/122) in the DCB group and 0.77 (94/122) in the plain balloon catheter group ( P = 0.001). The primary safety end point did not differ between groups ( P = 0.25). CONCLUSIONS AcoArt Orchid DCB showed better primary patency rates compared with plain balloon angioplasty for treating stenotic lesions in dysfunctional hemodialysis AV fistulae at 6 and 12 months. It required fewer repeated interventions and had comparable safety in 1 year. CLINICAL TRIAL REGISTRY NAME AND REGISTRATION NUMBER AcoArt III/Arterio-venous Fistula in China, NCT03366727 .

Abstract
OBJECTIVE The study aimed to compare the effectiveness of drug-coated balloon (DCB) and drug-eluting stents (DESs) to standard endovascular techniques like percutaneous transluminal angioplasty (PTA) and bare metal stent (BMS) for treating infrapopliteal artery disease. METHODS Including 8 DCB trials and 4 DES trials, this meta-analysis of 12 recent randomized controlled trials (RCTs) is comprehensive. We searched MEDLINE, EMBASE, Science of Web, Cochrane, and PubMed for this meta-analysis. We searched these databases for papers from their inception to February 2023. We also analyzed the references given in the listed studies and any future study that cited them. No language or publication date restrictions were applied to the 12 RCTs. The experimental group includes 8 DCB studies and 4 DES investigations, the DCB group is primarily concerned with the paclitaxel devices, whereas the DES group is preoccupied with the "-limus" devices. Key clinical outcomes in this study were primary patency and binary restenosis rates. This study's secondary outcomes are late lumen loss (LLL), clinically-driven target lesion revascularization (CD-TLR), limb amputation, and all-cause mortality. The evidence quality was assessed using Cochrane risk-of-bias. The PROSPERO registration number for this study is CRD42023462038. FINDINGS Only 108 of 1152 publications found satisfied qualifying criteria and contained data. All 13 RCTs have low to moderate bias. Drug-coated balloons and DESs were compared in the excluded study. The analysis comprised 2055 participants from 12 RCTs that met the inclusion criteria, including 1417 DCB patients and 638 DES patients. Drug-coated balloons outperform traditional methods in short-term monitoring of primary patency, binary restenosis, and CD-TLR. The benefits fade over time, and the 2 techniques had similar major amputation rates, mortality rates, and LLL. Drug-eluting stents outperform conventional procedures in primary patency, binary restenosis, and CD-TLR during medium-term to short-term follow-up. Comparing the 2 methods, major and minor amputations, death rate, and LLL were similar. CONCLUSION Comparison of DES and DCB with PTA or BMS shows that DES had better follow-up results. DCB has positive short-term results, but long-term effects differ, however, more research is needed to determine when DES and DCB should be used in medical procedures. CLINICAL IMPACT The provision of additional evidence to substantiate the advancement of drug-coated balloon (DCB) therapy in the treatment of lower limb arteriosclerosis obliterans, particularly in the below-the-knee area characterized by high calcium load and significant occlusion, is comparable in efficacy to conventional procedures. This finding is advantageous for the progress of interventional revascularization. The advancement and efficacy of DCB have resulted in improved treatment outcomes for medical practitioners in clinical settings. Our research incorporates the most recent randomized experiments.

Abstract
PURPOSE Percutaneous transluminal angioplasty (PTA) remains the mainstay of endovascular therapy for infrapopliteal chronic limb-threatening ischemia (CLTI), but outcomes have not been well characterized using high-quality data. The aim of this meta-analysis was to provide an updated benchmark for rates of primary patency and binary restenosis after PTA using prospectively collected, predominantly core-lab adjudicated randomized controlled trial (RCT) data. MATERIALS AND METHODS MEDLINE, EMBASE, Cochrane Central, and ClinicalTrials.gov were queried for RCTs published through November 2022 using PTA as a control arm and including patients with infrapopliteal CLTI. Studies were excluded if >25% of patients had intermittent claudication, other vessels were included, or primary patency or binary restenosis were not outcomes. Outcomes were analyzed using random effects models. This analysis was publicly registered (PROSPERO ID#394543). No funding was utilized. RESULTS Seventeen RCTs were included (1048 patients, 1279 lesions). Pooled primary patency rates using data from 6 RCTs were 68% at 6 months (95% confidence interval [CI]=45%-84%) and 66% at 12 months (95% CI=51%-79%). Pooled binary restenosis rates using data from 11 RCTs were 54% at 6 months (95% CI=33%-73%) and 60% at 9 to 12 months (95% CI=39%-78%). Significant heterogeneity was present in all outcomes (I2>50%, p<0.0001). Publication bias was not observed (Egger's p>0.1). CONCLUSIONS This meta-analysis provides estimates for binary restenosis and primary patency following PTA utilizing prospectively collected, predominantly core-lab adjudicated data. Results demonstrate 1-year primary patency rates that are 10% to 20% higher than what has been historically used in power calculations. These new estimates will help facilitate more accurate power analysis for future RCTs. CLINICAL IMPACT Rates of primary patency and binary restenosis after percutaneous transluminal angioplasty (PTA) have not been well-described using high-quality data, and investigators have been utilizing estimates of 40% to 50% and 45% to 65%, respectively, when performing power calculations for trials. This meta-analysis demonstrates using high-quality, prospectively collected, and predominantly core-lab adjudicated randomized controlled trial data that actual rates of primary patency are closer to 60% up to 1 year following PTA and provides the first meta-analysis estimate of binary restenosis rates up to 1 year after PTA. These estimates will help facilitate more accurate power calculations for future RCTs in this space.

Abstract
PURPOSE To evaluate 6-month outcomes of drug-coated balloon (DCB) angioplasty of infrapopliteal lesions in patients with chronic limb-threatening ischemia (CLTI). METHODS We analyzed 6-month follow-up data from the 10-center PRIME-WIFI prospective registry on 300 consecutive patients (33.000% female) with CLTI who underwent DCB angioplasty for infrapopliteal arterial lesions. The primary outcome was freedom from major adverse event (MAE), a composite of major amputation, all-cause death, and clinically-driven target limb reintervention (CD-TLR). Secondary outcomes included amputation-free survival (AFS), freedom from each primary outcome component, primary sustained clinical improvement, and quality of life (QOL) score. Independent risk factors of MAE were determined using Cox proportional hazards regression analysis. RESULTS A total of 409 infrapopliteal lesions in 312 limbs were treated with DCB, with 54.167% of the limbs being treated for isolated infrapopliteal lesions. By Kaplan-Meier analysis, at 6 months post- procedure (follow-up rate, 85.000%), freedom from MAE was 86.353%; AFS was 90.318%; and freedom from major amputation, all-cause death, and CD-TLR were 96.429%, 93.480%, and 95.079%, respectively. At 6-month follow-up, 83.590% of patients showed primary sustained clinical improvement, and QOL score (4.902±1.388) improved compared with that before procedure (2.327±1.109; p<0.001). Chronic renal insufficiency, chronic obstructive pulmonary disease, Rutherford grade, and postoperative infrapopliteal runoff score were independent risk factors for MAE within 6 months. CONCLUSION In CLTI, DCB angioplasty of infrapopliteal lesions yields acceptable early efficacy and safety. CLINICAL IMPACT This study evaluated the 6-month outcomes of DCB angioplasty in infrapopliteal lesions in CLTI patients by analyzing multicenter prospective data, showing that infrapopliteal DCB angioplasty can be performed with acceptable freedom from MAE rate, amputation-free survival rate, freedom from major amputation rate, survival rate, and freedom from CD-TLR rate. No patient experienced DCB-related intraoperative distal embolism. Chronic renal insufficiency, chronic obstructive pulmonary disease, Rutherford grade and postoperative infrapopliteal runoff score were independent risk factors for MAE within 6 months. Comparative real-world studies are needed.

Abstract
PURPOSE OF REVIEW Peripheral artery disease (PAD) is an increasingly prevalent but frequently underdiagnosed condition that can be associated with high rates of morbidity and mortality. While an initial noninvasive approach is the cornerstone of management, revascularization is often pursued for patients with treatment-refractory claudication or chronic limb-threatening ischemia (CLTI). In this review, we discuss the current state of endovascular interventions for PAD and explore the many new emerging technologies. RECENT FINDINGS The last decade has resulted in numerous advances in PAD interventions including the ongoing evolution of drug-coated devices, novel approaches to complex lesions, and contemporary evidence from large clinical trials for CLTI. Advances in endovascular management have allowed for increasingly complex lesions to be tackled percutaneously. Future directions for the field include the continued evolution in device technology, continued development of state-of-the-art techniques to revascularization of complex lesions, and increased collaboration between a largely multidisciplinary field.

Abstract
Endovascular revascularisation with paclitaxel-coated balloons for the treatment of peripheral artery disease has been shown to be an effective therapeutic option in the femoropopliteal segment. The antiproliferative effect of paclitaxel prevents restenosis. In contrast, in the infra-popliteal segment, the evidence is currently conflicting. However, there is evidence of an increased risk of amputation and mortality from the second year after angioplasty with paclitaxel-coated balloons. This may be due to a dose-dependent cytotoxic effect of paclitaxel. Sirolimus-coated balloons might therefore be an alternative because sirolimus is cytostatic rather than cytotoxic and thus has a wide therapeutic window.Three single-arm pilot studies (50, 25, and 50 patients, respectively) show that angioplasty with sirolimus-coated balloons leads to comparable results to those reported from paclitaxel-coated balloons (late lumen loss at 6 months: 0.29 mm; primary patency at 12 months: femoropopliteal 79%-82%, infra-popliteal 59%; freedom from target lesion revascularization at 12 months: femoropopliteal 83%-94%, infra-popliteal 86%). Randomised controlled trials comparing standard balloon angioplasty and paclitaxel-coated balloons for the treatment of intermittent claudication or chronic limb-threatening ischaemia are active and are expected to provide efficacy and safety results from mid 2024.This review presents the results of pilot studies on angioplasty with sirolimus-coated balloons for the treatment of peripheral artery disease and reviews currently ongoing randomised controlled trials.

Abstract
PURPOSE To evaluate the safety and effectiveness of excimer laser ablation (ELA) combined with drug-coated balloon (DCB) for atherosclerotic obliterans (ASO) of the lower extremities. MATERIALS AND METHODS From June 2019 to December 2020, all eligible patients were enrolled. Demographics, characteristics of lesions, complications, and follow-up information were collected and analyzed. The primary endpoint was major amputation-free survival (MAFS). Secondary endpoints included technical success, primary patency, bailout stent, distal embolization, target lesion reintervention (TLR), and ulcer healing rate. Major amputation-free survival and primary patency were calculated by Kaplan-Meier analysis. RESULTS A total of 71 patients were enrolled. Forty-eight (81.7%) patients presented critical limb ischemia (CLI) and 48.6% of them was calcification class 4 according to Peripheral Arterial Calcium Scoring System (PACSS). Chronic totally occluded (CTO) disease was the most common lesion in 66.0% of them and superficial femoral artery (SFA) was the most common segment in 59.6%. Technical success rate was 93.0%. One-year follow-up was finished in 25 (35.2%) patients. The primary patency and MAFS were 92.0%±27.6% and 96.0%±20.0% at 12 months, respectively. During the mean follow-up of 9.4±4.3 months, clinically-driven TLR occurred in 2 (2.8%) patients, and major and minor amputation occurred in 2 (2.8%) and 1 (1.4%) patient, respectively. CONCLUSION The early results demonstrated that ELA was an effective treatment in de novo, in-stent restenosis (ISR) and CTO lesions. Meanwhile, ELA could prepare the lumen for the use of DCB and reduce the implantation of stents, especially in segments unsuitable for stenting. Mid-term and long-term results need to be awaited.

Abstract
Chronic limb-threatening ischemia (CLTI) represents the end-stage form of peripheral arterial disease (PAD) and is associated with a very poor prognosis and high risk of limb loss and mortality. It can be considered very similar to a terminal cancer disease, reflecting a large impact on quality of life and healthcare costs. The aim of this study is to offer an overview of the relationship between CLTI, limb salvage, and mortality, with a focus on the need of a fast-track team-based management that is a driver to achieve better survival results. This review can be useful to improve management of this growing impact disease, and to promote the standardisation of care and communication between specialist and non-specialist healthcare professionals.

Abstract
Background Critical limb-threatening ischemia (CLTI) is a severe condition characterized by rest pain and ischemic tissue loss that affects 5% to 10% of people with peripheral artery disease. In the United States, there are few Food and Drug Administration-approved devices for the primary treatment of arteries below-the-knee (BTK). Unfortunately, all suffer from high restenosis rates due to intimal hyperplasia, elastic recoil, and untreated dissection because of a lack of scaffolding. The Esprit BTK system is a resorbable, drug-eluting scaffold device with the potential to address an unmet need in people suffering from CLTI because of infrapopliteal atherosclerosis. The LIFE-BTK (pivotaL Investigation of saFety and Efficacy of drug-eluting resorbable scaffold treatment-Below The Knee) randomized controlled trial (RCT) is a prospectively designed premarket evaluation of the Esprit BTK drug-eluting resorbable scaffold used in the treatment of those patients. Methods The LIFE-BTK trial enrolled 261 subjects with CLTI for the RCT and a further 7 subjects for a pharmacokinetic substudy. The objective of the RCT was to evaluate the safety and efficacy of the Esprit BTK scaffold compared to percutaneous transluminal angioplasty. The primary efficacy end point was a composite of limb salvage and primary patency at 12 months. The primary safety end point is freedom from major adverse limb events and peri-operative death at 6 months and 30 days, respectively. Clinical follow-up care is planned for 5 years. Conclusions Novel devices must be tested in RCTs to evaluate their safety and efficacy compared to the standard of care if we are to improve outcomes for this challenging group of patients.

Abstract
OBJECTIVES Catheter-directed thrombolysis is one of the main treatments for acute limb ischaemia. Urokinase is still a widely used thrombolytic drug in some regions. However, there needs to be a clear consensus on the protocol of continuous catheter-directed thrombolysis using urokinase for acute lower limb ischaemia. METHODS A single-centre protocol of continuous catheter-directed thrombolysis with low-dose urokinase (20,000 IU/hour) lasting 48-72 h for acute lower limb ischaemia was proposed based on our previous experiences. A retrospective study from June 2016 to December 2020 was conducted to evaluate the efficacy and safety of this protocol. The target lesion revascularisation, amputation and death were also monitored during follow-up. The Kaplan-Meier estimator was used for the subgroup analysis, and univariate and multivariate Cox regression analysis was applied to identify risk factors for reinterventions and death. RESULTS 90 lower limbs were involved, including 51 Rutherford Grade I, 35 Grade IIa and four Grade IIb. During a 60.8-h thrombolysis, 86 cases (95.5%) were considered effective according to the angiogram. No major bleeding complication occurred during thrombolysis, and one amputation occurred after. Freedom from target lesion revascularisation, amputation and death were 75.6%, 94.4% and 91.1% during a mean 27.5-month follow-up, respectively. According to the Kaplan-Meier estimator, aortoiliac lesions had lower reintervention rates than femoropopliteal lesions (Log-rank p = 0.010), and cases without narrowing atheromatous plaque had a lower reintervention rate (Log-rank p = 0.049). Age was an independent risk factor for death (p = 0.038, hazard ratio 1.076, 95% confidence interval 1.004-1.153). CONCLUSIONS The single-centre protocol of catheter-directed thrombolysis we proposed for acute lower limb ischaemia was effective and safe. Strict blood pressure control during catheter-directed thrombolysis ensured safety. Aortoiliac lesions and cases without narrowing atheromatous plaque had lower reintervention rates during follow-up.

Abstract
Lower limbs' arterial calcification is significantly associated with the clinical severity of lower extremity artery disease (LEAD) in patients undergoing hemodialysis (HD). However, the association between arterial calcification of the lower limbs and long-term clinical outcomes in patients on HD has not been elucidated. Calcification scores of the superficial femoral artery (SFACS) and below-knee arteries (BKACS) were quantitatively evaluated in 97 HD patients who were followed for 10 years. Clinical outcomes, including all-cause and cardiovascular mortality, cardiovascular events, and limb amputation were evaluated. Risk factors for clinical outcomes were evaluated using univariate and multivariate Cox proportional hazard analyses. Furthermore, SFACS and BKACS were divided into three groups (low, middle, and high), and their associations with clinical outcomes were evaluated using Kaplan-Meier analysis. SFACS, BKACS, C-reactive protein, serum albumin, age, diabetes, presence of ischemic heart disease, and critical limb-threatening ischemia were significantly associated with 3-year and 10-year clinical outcomes in the univariate analysis. Multivariate analysis showed that SFACS was an independent factor associated with 10-year cardiovascular events and limb amputations. Kaplan-Meier life table analysis showed that higher SFACS and BKACS levels were significantly associated with cardiovascular events and mortality. In conclusion, long-term clinical outcomes and the risk factors in patients undergoing HD were evaluated. Arterial calcification of the lower limbs was strongly associated with 10-year cardiovascular events and mortality in patients undergoing HD.

The efficacy and safety of different endovascular modalities for infrapopliteal arteries lesions: A network meta-analysis of randomized controlled trials. Front Cardiovasc Med 2022; 9:993290. [DOI: 10.3389/fcvm.2022.993290] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/13/2022] [Accepted: 10/27/2022] [Indexed: 11/10/2022] Open
Abstract
BackgroundEndovascular treatment has become the first-line therapy for infrapopliteal artery occlusive disease (IPOD), while the optimal endovascular method remains to be determined. We performed a network meta-analysis (NWM) of randomized controlled trials (RCTs) to simultaneously compare the outcomes of different endovascular modalities for IPOD.Methods and resultsThe Pubmed, Embase, and Cochrane databases were used as data sources. The NWM approach used random-effects models based on the frequentist framework. In total, 22 eligible RCTs (44 study arms; 1,348 patients) involving nine endovascular modalities or combinations [balloon angioplasty (BA), drug-coated balloon (DCB), drug-eluting stent (DES), atherectomy device + BA (AD + BA), AD + DCB, balloon-expandable bare metal stent (BMS), self-expanding stent (SES), absorbable metal stents (AMS), and inorganics-coated stent (ICS)] were included. BA had a lower 12-month primary patency rate than DCB (RR 0.50, CI 0.27, 0.93) and AD + DCB (RR 0.34, CI 0.12, 0.93). AD + DCB decreased 6-month TLR compared with AMS (RR 0.15, CI 0.03, 0.90), and DES decreased it compared with BMS (RR 0.25, CI 0.09, 0.71). DCB had a lower 6-month TLR rate than AMS (RR 0.26, CI 0.08, 0.86) and BA (RR 0.51, CI 0.30, 0.89). BA had a higher 12-month TLR rate than DCB (RR 1.76, CI 1.07, 2.90). According to the value of the surface under the cumulative ranking curve (SUCRA), AD + DCB was considered the best treatment in terms of primary patency at 6 months (SUCRA = 87.5) and 12 months (SURCA = 91). AD + BA was considered the best treatment in terms of 6-month TLR (SUCRA = 83.1), 12-month TLR (SURCA = 75.8), and 12-month all-cause mortality (SUCRA = 92.5). In terms of 12-month major amputation, DES was considered the best treatment (SUCRA = 78.6), while AD + DCB was considered the worst treatment (SUCRA = 28.8). Moreover, AD + BA always ranks higher than AD + DCB in the comparison including these two combinations. Subgroup analyses of modalities without stenting did not significantly change the primary outcomes.ConclusionADs showed noteworthy advantages in multiple terms for IPOD except for 12-month major amputation. AD + BA may be a better method for IPOD than AD + DCB. The efficacy and safety of ADs are worthy of further investigation.Systematic review registration[https://www.crd.york.ac.uk/prospero/], identifier [CRD42022331626].

Eur J Vasc Endovasc Surg 2022; 64:516-525. [PMID: 35973667 DOI: 10.1016/j.ejvs.2022.08.004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/10/2022] [Revised: 07/22/2022] [Accepted: 08/05/2022] [Indexed: 01/12/2023]
Abstract
OBJECTIVE Data on paclitaxel coated balloons (PCBs) for below knee (BTK) angioplasty exhibited conflicting efficacy results, and previous meta-analyses suggested an increased mortality and amputation risk highlighting the need for further research. The aim of this study was to investigate safety and efficacy of PCBs for BTK interventions in a real world cohort. METHODS Within a single centre cohort study, 552 consecutive patients were included undergoing BTK interventions with and without PCB use. Two year safety and efficacy results were compared in unadjusted and propensity score matched (PSM) analysis. RESULTS BTK interventions were performed in 157 patients with PCB angioplasty (100% Lutonix 0.014 inch drug coated balloon; Bard Lutonix, New Hope, MN, USA) and 395 patients with plain old balloon angioplasty (POBA). The majority of interventions (> 70%) were performed for chronic limb threatening ischaemia. Mean lesion length was 20.8 ± 12.6 cm; 61.2% in the PCB and 66.7% in the POBA group were occlusions. In the PCB group, more procedures were performed for re-stenotic lesions than POBA (28.5 vs. 17.2%). In PSM analysis (128 matched pairs), the primary efficacy endpoint was freedom from clinically driven target lesion revascularisation (CD TLR), which occurred in 70.1% in the PCB and 73.1% in the POBA group at one year (p = .85; McNemar test). Survival analysis suggested lower rates of major amputations in the PCB group in unadjusted (94.4% ± 2.1 vs. 89.2% ± 1.9 in the POBA group) and PSM analyses (97.2% ± 1.6 vs. 89.3% ± 3.5) through two years, while no differences were seen for CD TLR and all cause mortality between the groups. CONCLUSION In this all comer analysis, PCBs were found to be safe for BTK interventions with a signal towards lower amputation rates but no benefit was seen for repeat revascularisation.

Abstract
Limited data is available regarding the safety and effectiveness of drug-coated balloon (DCB) versus conventional percutaneous transluminal balloon angioplasty (PTA) in the treatment of critical limb ischemia because of infrapopliteal peripheral arterial disease. We conducted an updated meta-analysis to assess the safety and efficacy of DCB in the treatment of infrapopliteal disease. A database search of PubMed/MEDLINE, EMBASE, and the Cochrane Library was performed by 2 reviewers from inception through November 15, 2021. Randomized trials that compared DCB with conventional PTA in treating infrapopliteal arterial disease were included. The risk ratios (RRs) and 95% confidence intervals (CIs) were reported. A total of 9 trials were included (1,501 participants) in the study. The mean age was 71.1 ± 10.2 years. Regarding the primary end points, treating infrapopliteal arterial disease with DCB had a lower incidence of re-stenosis (RR 0.48, 95% CI 0.33 to 0.70, p = 0.0001) with no significant difference in all-cause mortality (RR 1.11, 95% CI 0.73 to 1.69, p = 0.61), compared with conventional PTA. With regards to the secondary end points, DCB usage was associated with a significant reduction in clinically driven target lesion revascularization (RR 0.54, 95% CI 0.35 to 0.84, p = 0.006) with no significant difference with regards to major target limb amputation and major adverse cardiovascular events (p ≥0.05). In conclusion, among patients with critical limb ischemia secondary to infrapopliteal artery disease, DCB usage was associated with a significantly lower number of restenosis and clinically driven target lesion revascularization compared with conventional PTA. There was no increase in all-cause mortality or major target limb amputation with the use of DCB.

Abstract
Purpose Evidence on efficacy and long-term safety of paclitaxel-coated devices is still conflicting. Therefore, this study aims to assess whether sirolimus-coated balloon angioplasty is safe and effective for the treatment of infra-popliteal occlusions in patients with chronic limb-threatening ischemia (CLTI). Study design The randomized controlled, single-blinded, multicentre, investigator-initiated study aims to enrol 230 participants with CLTI and infra-popliteal occlusions at up to 25 centres. Patients will be randomized in a 1:1 ratio to either sirolimus-coated balloon angioplasty or to plain old balloon angioplasty (POBA). Bailout stenting in case of flow-limiting dissection or ≥ 50% residual diameter stenosis is permitted. Outcome measures Primary outcome is the Kaplan–Meier estimate of primary patency at 6 months, defined as the absence of target lesion occlusion with restoration of in-line flow to the ankle. Key secondary outcome is non-inferiority in the proportionate occurrence of major adverse limb events and perioperative all-cause death at 30 days. Overall, participants will be followed for 36 months to assess further secondary efficacy and safety outcomes. Assumed gain of knowledge If sirolimus-coated balloon angioplasty turns out to be superior to uncoated-balloon angioplasty regarding patency of infra-popliteal lesions without safety signals, it could become a welcome treatment option for patients with CLTI. Trial Registration ClinicalTrial.gov Identifier: NCT04772300, German Clinical Trials Register: DRKS00024629. Level of Evidence Level 2a, randomized controlled trial.

Abstract
Successful revascularization of patients with peripheral arterial disease (PAD) requires a comprehensive understanding of the risk population and the available treatment options. Even the urgency of revascularization varies widely depending on the clinical presentation. Patients with intermittent claudication should undergo a structured exercise program before revascularization may become necessary, whereas acute limb ischemia is a medical emergency and must be revascularized within a few hours. Endovascular treatment techniques have evolved rapidly over the past 20 years. New technologies and procedural techniques allow even complex lesions to be successfully treated with endovascular techniques, and most patients can now be treated minimally invasively in line with an "endovascular first" strategy. Bypass surgery remains an important option for patients with advanced disease. The techniques used vary depending on the clinical presentation, location, and complexity of the lesion. Although the evidence for different techniques is limited, a variety of clinical and lesion factors are known to be critical for acute technical success and long-term patency rates. The use of paclitaxel-coated balloons and stents has been shown to significantly reduce restenosis and reintervention rates after femoropopliteal interventions. However, a late mortality signal associated with the use of these devices continues to be debated. After successful intervention, appropriate drug therapy and standardized follow-up should be established to prevent adverse limb events and reduce the high rate of cardiovascular events.

Abstract
ZusammenfassungDie kritische Ischämie der unteren Extremität aufgrund einer PAVK, bei der häufig
eine Mitbeteiligung der Unterschenkelarterien besteht, ist ohne
Revaskularisation mit einer schlechten Prognose vergesellschaftet. Für Patienten
mit diabetischem Fußsyndrom trifft dies in besonderem Maße zu. Auch finden sich
bei diesen Patienten nicht selten PAVK-Läsionen ausschließlich infrapopliteal.
Die endovaskuläre Rekanalisation wird in diesem Bereich zunehmend als Therapie
der ersten Wahl betrachtet. Der retrograde Zugang, spezielle Ballontechniken
sowie Atherektomiesysteme haben die technischen Erfolgsraten verbessern können.
Drug-eluting Stents und neue Drug-coated Ballons führen zu einer Verbesserung
der Offenheitsrate. Bei schwerer distaler PAVK ist allerdings eine
Revaskularisation häufig nicht möglich. Bei diesen sogenannten
„no-option“-Patienten könnte eventuell die Arterialisierung des tiefen
Venensystems in der Zukunft eine Rolle spielen.

Abstract
BACKGROUND Data are mixed concerning the safety and effectiveness of drug-coated balloons (DCBs) for treating below-the-knee (BTK) lesions. AIMS The aim of this study was to assess the safety and effectiveness of the IN.PACT 014 paclitaxel-coated balloon catheter versus conventional percutaneous transluminal angioplasty (PTA) for infrapopliteal chronic total occlusions (CTOs) in patients with chronic limb-threatening ischaemia (CLTI). METHODS The IN.PACT BTK randomised study is a prospective, multicentre, randomised pilot study. Fifty CLTI participants (Rutherford clinical category 4-5) with BTK CTOs were randomised 1:1 to DCB (N=23) or PTA (N=27). The primary effectiveness endpoint was late lumen loss (LLL) at 9 months post procedure. Safety outcomes up to 9 months included all-cause mortality, major target limb amputation, and clinically driven target lesion revascularisation (CD-TLR). RESULTS Mean lesion length was 215.41±83.81 mm in the DCB group and 218.19±80.43 mm for PTA (p=0.806). The 9-month angiographic LLL was 0.892±0.774 mm for the DCB group and 1.312±0.720 mm for the PTA group (p=0.070) in a classic analysis, and 0.592±0.944 mm for DCB and 1.260±0.810 mm for PTA (p=0.017) in a subsegmental analysis. The Kaplan-Meier estimated freedom from CD-TLR up to 9 months was 91.1% for DCB and 91.8% for PTA (log-rank p=0.942). At 9 months, 1 patient died in the DCB group and 2 in the PTA group (p=1.000); there were no major target limb amputations in either arm. CONCLUSIONS The 9-month subsegmental LLL was lower after treatment with the IN.PACT 014 DCB compared with PTA with no differences in safety or revascularisation events in a small complex population of patients with BTK CTOs.

Abstract
BACKGROUND The aim of this study is to evaluate the 5-year clinical outcome of the DEBATE-BTK (Drug-eluting balloon for below-the-knee angioplasty evaluation) trial. METHODS The DEBATE-BTK was a single-center, randomized trial that enrolled 132 diabetic patients with critical limb ischemia. Subjects were randomized 1:1 to DCB or plain old balloon angioplasty (POBA). Major clinical endpoints were, freedom from all-cause death, freedom from clinically driven target lesion revascularization (CDTLR) and the occurrence of major amputation. Additional analysis were conducted to assess overall survival in patients treated with DCB compared to those treated with only POBA in the entire 5-years period and to test the correlation between paclitaxel dose exposure (in terciles) and overall survival. RESULTS Freedom from all-cause death at 5 years was 63.1% (41/65) in DCB vs. 53.7%(35/67) POBA patients (p = 0.4). Freedom from CDTLR was 82% in DCB and 63% in POBA patients (p = 0.002) at 1 year and 63 versus 54% at 5 years respectively P = 0.07. One patient in DCB and 2 patients in POBA underwent a major amputation of the target limb. During the 5-year follow-up, 24 patients originally randomized to POBA received DCB treatment for additional limb revascularization. According to DCB treatment in all the 5 years period, overall survival was 66.3.% (30/89) in DCB versus 40%(26/43) in POBA patients, p = 0.003. CONCLUSIONS Overall survival at 5-year was similar in DCB treated patients compared to POBA. Moreover, survival was higher in patients that received DCB angioplasty at any time of the 5 years period. LEVEL OF EVIDENCE Level 1b, Individual inception cohort study with > 80% follow-up.

Abstract
PURPOSE Drug-coated balloon angioplasty (DCBA) has been studied as a potentially superior option compared to conventional percutaneous transluminal angioplasty (PTA) in treating below-the-knee (BTK) arteries in chronic limb-threatening ischemia (CLTI). The aim of this study is to examine the cost-effectiveness of DCBA versus PTA in BTK arteries based on a randomized controlled trial. MATERIAL AND METHODS A prospective economic study was embedded in a randomized controlled trial of 138 patients with CLTI. Resource use and health outcomes were assessed at baseline, and at 3, 6 and 12 months post-intervention. Costs were calculated from a societal perspective and health outcomes measured using quality-adjusted life years with probabilistic sensitivity analysis performed to account for subject heterogeneity. RESULTS Compared with participants randomized to receive PTA, participants randomized to DCBA gained an average baseline-adjusted quality-adjusted life years (QALYs) of .012 while average total costs were USD$1854 higher; this translates to an incremental cost-effectiveness ratio (ICER) of US$154,500 additional cost per QALY gained. However, the estimate of ICER had substantial variance with only 48% of bootstrap ICERs meeting a benchmark threshold of US$57,705 (the average gross domestic product (GDP) per capita of Singapore). CONCLUSION The use of DCBA in BTK arteries in CLTI patients was not cost-effective compared with PTA. LEVEL OF EVIDENCE 2, Randomized trial.

Abstract
Cardiovascular medicine is facing several challenges in the current era, dominated by the rapid spread of a previously unknown virus around the world. Indeed, the 2020 COVID-19 pandemic set the course of cardiovascular science and education in an extraordinary way, hogging the attention of the medical community. Notably, while COVID-19 impacted research progress, there has been considerable effort in exploring topics of great interest, from the management of acute coronary syndromes to new horizons in the treatment of heart failure, from novelties in the surgical treatment of cardiovascular disease to new data on implantable cardiac devices, and from new diagnostic applications of multimodal imaging techniques to relevant basic science findings. Minerva Cardiology and Angiology, formerly Minerva Cardioangiologica, has strived to inform its readers on these topics and novelties, aiming for a succinct yet poignant melding of timeliness and accuracy. Accordingly, the purpose of this narrative review is to highlight and summarize the major research and review articles published during 2020. In particular, we provide a broad overview of the novelties identifying six major areas of interest in the field of cardiovascular sciences in which new evidences have contributed to improving prevention, diagnosis and treatment of heart and vessels diseases.

Abstract
The CIRSE Standards of Practice Committee established a writing group that was tasked with producing up-to-date recommendations for performing below-the-knee revascularisation, taking into account data on novel techniques, devices, and long-term outcomes that have emerged over the last decade. CIRSE Standards of Practice documents are not clinical practice guidelines or systematic reviews of the literature. This document is not intended to impose a standard of clinical patient care but recommends a reasonable approach to and best practices for performing below-the-knee revascularisation.

Abstract
BACKGROUND Drug penetration into the deeper arterial wall of heavily calcified lesions is one of the limitations of drug-coated balloons and drug-eluting stents in vascular interventions. The Temporary Spur Stent (TSS) system is characterized by a self-expanding nitinol stent that is uniformly covered in radialspikes, which, when coated, should allow a deeper penetration and longer retention of the drug into the diseased artery walls by penetrating through the calcified plaques. MATERIALS AND METHODS AND RESULTS Uncoated TSS and paclitaxel (PTX)-coated TSS systems have been deployed in porcine peripheral arteries. Four weeks after the deployment of uncoated TSS systems, no adverse vascular remodeling or neointimal formation in the treated vessel segments were noticed. PTX-coated TSS systems transferred 9%±7% of the drug that was on the device to the targeted vessel area (196±163 ng PTX/mg arterial tissue) and the addition of the fluorescent dye Nile red to the coating showed that the spikes promote the transfer of the coating to the deeper layers of the vessel wall. The PTX-coated TSS systems showed a significant reduction in neointimal proliferation compared to the uncoated TSS systems: quantitative angiography showed a vessel diameter stenosis of 37.2%±11.0% and 16.4%±8.8% 4 weeks after the treatment with uncoated and PTX-coated TSS systems, respectively. CONCLUSION The treatment with the TSS system was well tolerated and the spikesfacilitate the transfer of the coating into deeper layers of the vessel wall. Moreover, the PTX-coated TSS systems effectively inhibit neointimal proliferation.

Abstract
BACKGROUND The aim of MERLION (NCT04073121) was to evaluate the outcomes of the mono or combination therapy of the iVascular LuminorTM drug coated balloon (DCB) and AngioliteTM drug eluting stent for treatment of TASC II C/D tibial occlusive lesions in Asian patients presenting with chronic limb threatening ischemia (CLTI) from Singapore. METHODS MERLION was a prospective, non-randomized, single arm, observational, multicenter clinical study. Complication-free survival at one month was the safety endpoint. Immediate technical success, 12-month primary vessel patency, limb salvage, freedom from target lesion revascularization (TLR) and amputation free survival (AFS) were the efficacy endpoints of interest. RESULTS 50 patients were included. There were 32 males (64% males; mean age 66.4±8.9 years). Majority were Rutherford 5 severity (41/50; 82%). Co-morbidities included diabetes mellitus (47/50; 94.0%), end-stage renal failure (25/50; 50.0%), and hypertension (44/50; 88%). 66 atherosclerotic lesions were treated (47 de novo and 19 restenotic; 60.6% TASC C and 39.4% TASC D). Mean lesion length treated was 13.7±9.5cm. There was 100% technical success. There were 3/66 (4.5%) bailout stenting for severe flow limiting dissections. 12-month primary tibial patency was 34/49 (69.4%) and freedom from TLR was 40/49 (81.5%). AFS was 74.0% (37/50). At 12 months, mean Rutherford scores improved from 100% (Rutherford score>3) at baseline to 31% at 12 months (p<0.05) and wound healing rate was 65.7%. CONCLUSIONS The iVascular LuminorTM DCB is safe and efficacious in treating highly complex infra-popliteal atherosclerotic lesions in an otherwise challenging frail population of CLTI patients from Singapore.

Abstract
The below-the-knee arterial tree is the thinnest of all the leg vessels and is an important path for blood flow to the foot. Hence, lesions including stenosis, especially obstruction, may lead to critical limb ischemia which represents the most severe clinical manifestation of peripheral arterial disease. It is characterized by the presence of ischemic rest pain, ischemic lesions, or gangrene attributable to the objectively proven arterial occlusive disease. Typically, the atherosclerotic disease process involving the below-the-knee arterial tree is diffuse in the majority of patients. The cornerstone of therapy is vascular reconstruction and limb salvage. Revascularization should be attempted whenever technically possible, without delay, in patients presenting critical limb ischemia and when the clinical status is not hopelessly non-ambulatory. Therefore, endovascular treatment can become the gold standard for the full range of patients including below-the-knee, limiting the clinical role of the classically trained surgeons.

Abstract
BACKGROUND Local administration of growth-inhibiting substances such as paclitaxel or sirolimus could reduce the risk of restenosis. In the drug coated balloon (DCB) technology the coating and the applied dose seem to play a major role. The aim of the present preclinical studies was to investigate the efficacy and safety of a specific DCB with paclitaxel as active ingredient and magnesium stearate as excipient. METHODS Evaluation of the coating, drug release and transfer was done ex vivo and in vivo on peripheral arteries. A porcine coronary stent model was chosen to provoke intimal thickening. Conventional uncoated balloons were compared with paclitaxel urea and paclitaxel magnesium stearate coated balloons. QCA and histomorphometry was performed on treated vessels. Three areas of the heart were histologically examined for pathological changes. RESULTS QCA and histomorphometry revealed no differences in baseline data between treatment groups. All DCB groups showed a significant reduction of angiographic and histologic parameters describing neointimal formation 4 weeks after treatment (e.g. mean angiographic late lumen loss all coated 0.31 ± 0.18 mm versus 0.91 ± 0.37 mm in the uncoated balloon group). There were no device-related animal deaths or clinical abnormalities. In spite of very slight-to-slight microscopic findings limited to small arterial vessels in downstream tissue there was no change in left ventricular ejection fraction or angiographic presentation of small side branches of treated arteries. CONCLUSION Paclitaxel DCB using stearate as excipient show a high efficacy in reducing neointima formation after experimental coronary intervention. No evidence of myocardial damage resulting from distal embolization was found.
